Sir i already tried for this one... same problem happened.. please sir suggest me any other things according to my laptop model.. i guess it have PCI\VEN_1022&DEV_7804&CC_0106 & PCI\VEN_1022&DEV_7801&CC_0106 hardware but common AHCI drivers don't work on it... may be it need specific drivers according to their model no HP15-g004AU and Asus x552e respectively... sir please help..
